Earth was invaded long before I was born. They were scavengers, searching the galaxy for a plentiful source of food. After landing here they developed a voracious taste for human flesh. In the decades that followed, over-harvesting totally wiped out all adults. The youth had always been considered off-limits, but the alien leadership began distributing young males to continue feeding their demanding population. The terror of being stripped naked and tied down to a blood stained table, then slowly eaten alive by a whole family of them is beyond my imagination.
Girls like me are housed in massive breeding factories. The alien staff select the most well-endowed boy at each location to keep everyone pregnant. The older girls get milked three times a day by large suction machines. They say it feels wonderful so I can’t wait to try it. There are special vitamins to make their boobies grow bigger and produce more milk for the young ones.
Today is very special, because I am scheduled to be inseminated for the first time since reaching the required age. I was taken to the room where it happens and instructed to remove my clothing. As the last article fell to the floor the attendant directed me to a padded table. I felt so vulnerable laying there fully exposed in the same room with one of them. The way the thing stared made me feel like my tender body was about to be ripped apart and devoured. There was a camera on the ceiling with a blinking red light pointed in my direction. I watched as the monster turned and spoke to a box on the wall.
“Send in the breeder.”
A door at the far end of the room slid open with an abrupt hiss revealing a slender naked boy. He stood in the doorway looking at me and I saw his penis begin to grow. Perhaps he thought I was pretty. In the time it took him to make his way across the room, it became obvious why he was chosen as a breeder.
He began gently messaging my twinkie while standing at the foot of the table between my legs. I wasn’t used to being touched by a boy like that, but I started to enjoy the attention. The alien slathered a clear gel all over his shaft while my body tensed in apprehension.
“You may begin” directed the creature, showing little emotion.
